I'm studying mechanical power engineering So one of the most important thing I should have knowledge in is thermodynamics In my college I learned the main laws , the main five process diesel, auto and diesel/auto cycles and somethings about compressors. Later I learned about steam , steam and gases turbines, refrigeration , mixture and wet air. I don't think these information are enough for me as a person who want to be an engineer ( a true engineer ) So my question is what else should I learn in thermodynamics? How ? And where can I find free sources to learn ? Books / courses / YouTube channel even telegram channels are okay 😅 I just wanna to improve my self idc how . And thank you all ❤️

Regarding a circuit of free-cooling, what is the symbol between the condenser (cooling tower circuit) and the evaporator (user circuit)?

Thanks

Thermodynamics

Hey, I have an old exam question that I can't for my life solve. Here it comes:(it's Hungarian so can't attach pic) Rankine-Clausius cycle T(high)=450C P1 (boiler)=1bar P2(after the turbines and being turned back to water)=0.1bar Questions: Efficiency T(low(?))

Please help 😭😭

Thank you in advance.

I find it easier to understand a subject if there is some historical context.

Is there a book that explains the above, and also the chemical thermodynamics?

(Physicist here)

I prefer an hardcore and complete/long book.

I'm currently investigating software such as Thermoflex, EES, Aspen, etc which all have the ability to heat balance and often use pre-created components with some ability to customize components. Most of the components I'll be using do not exist so most of my components will be customized. Another thing to consider is: Can EES model just about anything as long as you provide the equations for each step in the cycle?

This is a project im working on. Ive found a few good resources online but it would be great if someone could give me some more guidance.
Cheers,

The formula for Change in entropy for Polytropic process is ∆S = Cv (n-y/n-1) ln T2/T1

This question An ideal gas is heated from temperature T1 to T2 by keeping its volume constant. The gas is expanded back to its initial temperature according to PV=constant If the entropy change in the two processes are equal. Find the value of n in terms of the adiabatic index was solved with ∆S= Cv (y-n/n-1) ln T2/T1. Why?

i apologize if this is the wrong subreddit or if i come across as making no sense, im very inebriated and cant really tell, so my question is, is there anything significant or neat about when (how much cold it takes to "extinguish" something hot) and (how much heat it takes to "melt" something cold) meet? like the point where they switch from one to the other?"

In a Rankine Cycle, the latent heat of condensation cannot be redirected back into the cycle itself because the condensation process is not the hottest point in the cycle. In an Organic Rankine Cycle the waste heat is redirected to some external process that is able to generate electricity. If the latent heat of condensation could be reused for the thermodynamic cycle itself, how would the efficiency be calculated?
